Fiber strengthened concrete is a composite cloth consisting of combinations of cement, mortar, or concrete and discontinuous, discrete, uniformly dispersed appropriate fibers. Some of the fibers that may want to be used are metal fibers, polypropylene, nylon, asbestos, coir, glass and carbon. Fiber reinforcement is oftentimes used to supply longevity and ductility to brittle cementations matrices. Natural fibers such as coconut fibers and banana fibers broadly reachable global in massive quantity. This find out about offers use of agricultural waste fabric into concrete, which stronger the residences of concrete and makes surroundings eco- friendly. The addition of coconut fibers and banana fibers extended the engineering residences of the concrete sturdiness and tensile strength. Coconut fibers and banana fibers are environmental pleasant and existing essential attributes such as low density, mild weight, low cost, non –corrosiveness, excessive tensile strength. In this find out about coconut fibers 80% and banana fibers 20% as composite had been brought to M20 grade concrete in specific share 0%, 0.5% 1.5%, 2.0%, 2.5%, by way of weight of cement. The widespread cubes, cylinders, and beams for traditional concrete and coconut fibers and banana fibers bolstered concrete had been organized and examined in the laboratory. Mechanical homes such as compressive, break up tensile and flexural power have been determined. The end result suggests that, compressive strength, cut up tensile energy and flexural energy marginally improved. 1.INTRODUCTION Concrete is the most broadly used development fabric all over the world with improvements in science and technological know-how in building industry, the scope of concrete as a structural material, has widened. Since concrete is vulnerable in anxiety and flexure most commonly, it is strengthened the usage of metal reinforcing bars. However utilization of metal reinforcement is expensive. Considerable efforts international to add a number kinds of fibers to concrete so to make it extra robust long lasting and economical. Plain concrete is a brittle material. Concrete except any fibers will boost cracks due to plastic shrinkage, drying shrinkage and adjustments in quantity of concrete. Development of these micro cracks motives elastic deformation of concrete. In order to meet the required values of flexural strength, fibers are used in ordinary concrete. The addition of fibers in simple concrete will manipulate the cracking due to shrinkage and additionally minimize the bleeding of water in concrete. Natural fiber such as coconut fiber; banana fiber has positive bodily and mechanical traits that can be utilized successfully in the improvement of strengthened concrete material. 2.MATERIALS USED Cement: Ordinary Portland Cement of 53 grade Fine aggregate: Locally available river sand passing through I.S.S. 4.75mm sieve How to cite this paper: R.

The time taken is noted by using a stop watch. ?The vicat mould is placed on the non-porous plate and is filled with the prepared cement paste and the surface of the pate is made smooth in level with the mould by using a trowel. ?By shaking the mould slightly air if any, is expelled from the sample. ?The non-porous plate and the mould are placed under the needle. ?The needle is gently lowered to touch the surface of the plate and then the indicator adjusted to show zero reading. ?The needle is released quickly allowing it to penetrate in to the paste. ?When the needle comes to rest, the reading on the index scale is noted. The mildew had been stuffed with sparkling concrete one 3rdheight and compacted by means of ability of tamping rod. The equal manner is adopted to fill the last peak of mildew and sooner or later the pinnacle floor is completed clean with trowel.
